Side A adds a genuine user-facing feature (connectivity/topology stats in CLI output) with clear formatting logic and two solid unit tests, with no behavioral risk. Side B claims to remove 'dead code' but the diff shows the change actually alters reducer behavior (items and pairs are now registered even for a zero-ratio vote), contradicting its own justification and introducing a subtle state inconsistency risk despite the tests being updated to match.

council reasoning
A adds lasting user-facing value by surfacing existing connectivity stats (density, components, comparisons-to-connect) in pair CLI output with focused formatting and tests. B only deletes a redundant zero-ratio early-return already enforced at parse/handler boundaries and adjusts the related test, which is correct hygiene but much smaller project impact.
Side A adds a new user-visible capability by formatting and displaying existing graph connectivity statistics in the CLI, including density, connectedness, and pluralization, and backs it with unit tests covering connected and disconnected cases. Side B is a small cleanup that removes a redundant zero-ratio guard and updates a test to reflect existing behavior (items/pairs are still registered while zero-weight edges are skipped), which is useful but narrower in lasting impact.

[047b82bd] Remove redundant zero-ratio guard from reducer. Zeros are already rejected at the DSL parser and browser handler; the guard in apply_vote was dead code. The negative clamping stays since add_edge_weight already skips weight-0 edges correctly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
